Servers go dark. Data evaporates. And your boardroom scrambles as nation-states flex cyber muscles in the next hot zone.
That’s the nightmare Mandiant just mapped out in their ‘Proactive Preparation and Hardening Against Destructive Attacks: 2026 Edition.’ Not hype — cold, hard analysis from frontline responders who’ve seen wipers like BABYWIPER erase evidence in real ops.
Look, destructive attacks aren’t daily spam. They’re rare, high-stakes nukes deployed when geopolitics boil over. Think NotPetya in 2017, crippling Ukraine and spilling into Maersk’s $300 million nightmare. Mandiant’s betting on more: elections, Taiwan tensions, Middle East flare-ups. Their data? Instability spikes these hits 5x.
But here’s my edge — and Mandiant glosses this — it’s hybrid warfare 2.0. Remember Stuxnet? Destructive code as diplomacy. By 2026, expect AI-tuned wipers that mimic legit admin tools, dodging EDR like ghosts. Orgs ignoring this? They’ll be the new case studies.
Why Destructive Attacks Spike During Conflicts?
Conflicts breed chaos. Cyber’s cheap — no missiles needed. Mandiant pulls receipts: threat actors hit destructive when reprisal risks stay low, but objectives scream high reward.
Threat actors use destructive malware to destroy data, eliminate evidence of malicious activity, or manipulate systems in a way that renders them inoperable.
Spot on. Wipers, modified ransomware, custom payloads. Frequency? Low, but impact? Catastrophic. Russia’s Ukraine playbook showed 20+ destructive campaigns since 2022. Scale that to 2026’s powder keg.
Organizations aren’t helpless, though. Mandiant’s table — yeah, that summary goldmine — prioritizes external-facing assets first. Enumerate ‘em. Harden ‘em. Because attackers probe here: RDP weak, forgotten IIS servers begging for shells.
Patch ruthlessly. Segment networks. But don’t stop at tech — resilience demands crisis muscle.
Out-of-band comms? Non-negotiable. Picture Slack nuked, email toast. Pre-build that side-channel with stakeholders baked in. I’ve seen firms fumble this; recovery drags weeks.
Plans? Manual ops for core functions. Prioritize apps — CRM before email. Map dependencies or watch dominoes fall.
Vendors? Lock ‘em in now. IR teams, lawyers, negotiators. Practice restores with immutable backups. Test RTOs quarterly. Mandiant’s Google SecOps rules catch the sneaky stuff: BABYWIPER file erasure, rundll32 tricks, Defender exclusions batched in one cmd.
Fifteen rules listed. Deploy ‘em. They’re tuned for anomalies — divergence from your baselines.
Is Your Endpoint Ready for 2026 Wipers?
Endpoints are ground zero. Attackers love ‘em: cmd spawning services, DLLhost masquerading, fsutil zeroing files.
Mandiant flags: services tweaking CurrentControlSet, bcdedit mods, wbadmin deletes. PowerShell nuking content to zero. DD overwriting disks.
Custom detections beat signatures here. Why? Actors morph fast. Baselines catch the weird: scheduled tasks from system processes, backdoors dumping DLLs.
But endpoints alone flop without network layers. use EDR, NDR — broad heuristics snag 80% early. Supplement with Mandiant’s pack: Frontline Threats, Hunting Rules.
Update alert: MDM abuse rising. Threat actors hijack Intune, Jamf for mass wipes. Block that — audit exclusions, monitor bulk deploys.
Scalable? Damn right. Start with high-value assets. Inventory endpoints. Baseline cmds. Alert on outliers.
Resilience isn’t bolted-on. It’s governance. Crisis teams practicing out-of-band restores while C-suite eyes immutable offsite backups (Veeam, Cohesity crushing it here, market up 25% YoY).
Market dynamics scream invest: cyber insurance premiums jumped 40% post-2023 wipers. Firms with these playbooks shave claims 30%, per reinsurers.
Mandiant’s sharp — no fluff. But their PR spin? Downplays org inertia. Most skip exercises; 70% fail first restore per Gartner. My call: mandate tabletop sims or bleed cash.
External assets next. Public-facing? Crawl ‘em weekly. Shodan, your friend. Block RDP to internet — VPN only. CIS benchmarks, not optional.
Then internals: privilege escalation blocks. LAPS for locals. Just-in-time everywhere.
Detection deep-dive: copy from Downloads? Red flag. Multiple Defender exclusions? EDR scream.
Google SecOps users, grab those packs. Others? Translate to Splunk, Elastic.
Unique angle: 2026’s twist — supply chain wipers. Like SolarWinds but destructive. Mandiant hints; I predict: MSPs hit first, rippling out. Vet vendors harder.
Bottom line? This ain’t optional. Geopolitics guarantee attempts. Prep now — or join the wiped.
Organizational Resilience: Beyond Tech
Tech hardens. Resilience endures.
Pre-validate out-of-band: Signal groups, satellite phones. Decouple from AD.
Contingencies: manual payroll, air-gapped ledgers.
Third-parties: SLAs for IR, recovery.
Exercises: full restores. Immutable backups only — no live snapshots for ransoms.
Mandiant nails it. Execute or regret.

Frequently Asked Questions
What are destructive cyberattacks?
Attacks using wipers or malware to erase data, wipe evidence, or brick systems — often tied to nation-state conflicts.
How do I prepare for Mandiant’s 2026 destructive threats?
Harden endpoints/networks with their detection rules, build out-of-band comms, practice immutable restores quarterly.
Are Google SecOps rules enough against wipers?
They’re a strong start — 15+ rules for anomalies — but layer with baselines, EDR, and resilience planning.
